Examples of volumetric lighting are seeing sunbeams shining through a window and seeing sunbeams radiating when the Sun is below the horizon, also known as crepuscular rays. The term seems to have been introduced from cinematography and is now widely applied to 3D modeling and rendering , especially in the development of 3D video games .
Extreme UV and X-rays are produced (left of wavelength range) but comprise very small amounts of the Sun's total output power (area under the curve). Although the solar corona is a source of extreme ultraviolet and X-ray radiation, these rays make up only a very small amount of the power output of the Sun (see spectrum at right).
Backstays of the sun, [9] a nautical term, from the fact that backstays that brace the mast of a sailing ship converge in a similar way; Buddha rays [2] God rays, used by some members of the computer graphics industry [10] Jacob's Ladder [2] Light shafts, sometimes used in the computer graphics industry, such as the game engine Unreal Engine [11]

Crepuscular rays are noticeable when the contrast between light and dark is most obvious. Crepuscular comes from the Latin word crepusculum, meaning "twilight". [2] Crepuscular rays usually appear orange because the path through the atmosphere at dawn and dusk passes through up to 40 times as much air as rays from a high Sun at noon.
Richard is depicted as seated between a crescent and a "Sun full radiant" [1] A representation of the sun is used as a heraldic charge. The most usual form, often called sun in splendour or in his glory, consists of a round disc with the features of a human face surrounded by twelve or sixteen rays alternating wavy and straight.
Their first job as the Renegades (in the late 1950s) was at the Seaside Session at Palisades Park in Pacific Palisades. In 1961 they teamed up with Larry Tremaine, and became Larry Tremaine and the Renegades, a rock and roll cover band, consisting of: Larry Tremaine, Steve O'Riley (now deceased), Marty DiGiovanni, Rick Henn, Eddy Medora (November 28, 1945 – October 27, 2006), and Vince ...
The terms "chemical rays" and "heat rays" were eventually dropped in favor of ultraviolet and infrared radiation, respectively. [15] [16] In 1878, the sterilizing effect of short-wavelength light by killing bacteria was discovered. By 1903, the most effective wavelengths were known to be around 250 nm.
